Beyond Raw Iso-Casein PM is a protein supplement made by GNC. It is designed to boost muscle mass, promote recovery and provide “restful sleep support”.
The product contains 25g of protein per portion – all of which is derived from micellar casein isolate. When taken before bed, this slow-digesting protein is said to help reduce muscle breakdown during sleep.
The supplement also features 5.5g of branched-chain amino acids (BCAA), which are believed to support muscle recovery after exercise.
In addition, Iso-Casein PM contains Suntheanine (a patented form of L-theanine), which is thought to promote relaxation and sleep.
Each 970g container provides 25 servings.
